Electrically shielded connectors

Abstract

A shielding device, as for spring pins, is provided by providing a base having shielding holes, grounding holes, and a trough connecting them with an interconnected covering, providing within the shielding holes insulators with element holes therethrough.

What is claimed is: 
     
       1. An electrically shielding device which comprises: a base, said base being formed of insulating material, and having therein a shielding hole and   a shield connecting hole,     said shielding hole having positioned therein a metallic shield therearound,   an insulator within said shield, and   an element hole in said insulator, and     said shield connecting hole having positioned therein an electrically conductive layer,     said layer being in electrical communication with said shield.     
     
     
       2. The device of claim 1 in which said shield and said layer are coatings. 
     
     
       3. The device of claim 2 in which one continuous coating provides said coatings and said electrical communication. 
     
     
       4. The device of claim 3 in which said continuous coating is of plated metal. 
     
     
       5. The device of claim 4 in which said metal is electroless nickel. 
     
     
       6. The device of claim 2 in which said base and said insulator are of plastic. 
     
     
       7. The device of claim 6 in which said insulator is glass-loaded polyphenylene sulfide and said insulator is of castable polytetrafluoroethylene, and said metal is electroless nickel. 
     
     
       8. The device of claim 3 in which a trough connecting said shielding hole and said shield connecting hole is covered by said continuous coating. 
     
     
       9. The method of fabricating a shielding device which comprises forming an insulating base, providing therein a first hole and a second hole, coating said base over said holes with a layer of conductive material, placing in said first hole an insulating material with a third hole therethrough, and electrically interconnecting the coatings in said first and second holes. 
     
     
       10. The method of claim 9 in which said base is coated overall, and top and bottom surfaces are thereafter cut to electrically segregate said first and second holes. 
     
     
       11. The method of claim 10 in which a channel connecting said first hole and said second hole is coated therewith to provide said electrically interconnecting.
